    • When inverter control is implemented in a refrigerator or the like, the rotating speed of a compressor motor is often operated at the preset minimum rotating speed. At this time, there has been a problem that when the DC voltage is boosted, the efficiency of the circuit drops due to switching loss in the power element. Still more, when the DC voltage is boosted even at the minimum rotating speed, the lowest voltage of the DC voltage must be controlled at 163 V or more including the fluctuation of the voltage. Therefore, there has been a problem in that the efficiency of the compressor motor also drops. To avoid these problems, when the temperature within a compartment of a refrigerator is cooled and approaches a preset temperature, and when a conduction ratio of the compressor motor falls below a preset value or a command on a rotating speed of the compressor motor becomes a preset rotating speed and the actual rotating speed also becomes the preset rotating speed, the control of the converter control circuit is turned off.
    • 当在冰箱等中实现变频器控制时,压缩机电动机的转速通常以预设的最小转速运转。 此时存在直流电压升高的问题,由于功率元件的开关损耗,电路的效率下降。 此外,即使在最小旋转速度下直流电压升压时,直流电压的最低电压必须控制在包括电压波动在内的163V以上。 因此,存在压缩机电动机的效率也下降的问题。 为了避免这些问题,当冰箱的室内的温度被冷却并且接近预设温度时,并且当压缩机电动机的导通比低于预设值或者压缩机电动机的转速的指令变为预设值时 转速和实际转速也成为预设的转速,转换器控制电路的控制被关闭。

    • A hot melt ink jet printer includes a central opening provided on its main frame casing that can be opened and closed by one motion. An ink pellet setting opening to allow ink pellets of different colors to be supplemented separately is provided on the top surface of the main frame casing. An inner cover including an ink case that covers over the ink pellet supplementing opening and a side cover body constructed to be joined to one side of the ink case is installed, but allowing for vertical pivotal motion, to close the central opening.

    • A transmitting apparatus based on phase modulation including a data encoding circuit (100), a phase locus control circuit (200) and a modulator (300). The data encoding circuit (100) divides input data to be transmitted into a predetermined number of bits, and sequentially outputs them as segmented data. The phase locus control circuit (200) outputs a phase locus control signal representing each of the segmented data by three values of a positive direction, a negative direction and a non-rotation state of the phase rotation. The modulator (300) changes the phase of a transmission signal in response to the phase locus control signal. Using the phase rotation direction information of the three values makes it possible to reduce transmission bits, to increase transmission speed and transmission capacity.
